Thanks again for this — you were more right than you knew. The chains existed (drift steel = refined ingot + salvaged scrap, weapons are paid in refined goods), but locked recipes hid their ingredients, so the whole thing was invisible until level 30. Just shipped v0.1.1: every recipe now shows its full chain from minute one, upgrade costs show where materials come from, and the inventory shows what each resource is used in. Would love to hear if it reads better now.
